EVIL ENERGY AN6 Flare to AN6 ORB Male O-Ring Adapter 4pc — 6061-T6 Aluminum, NBR O-ring, 1500 PSI

EVIL ENERGY 6AN flare-to-AN6 ORB male O-ring adapter (4 pieces) is a high-strength aluminum fitting that converts a 37° flare AN connection to an ORB port sealed with an O-ring.

This adapter lets you join AN6 flare hoses or tubes to AN6 ORB female ports without modifying existing lines. Built from 6061-T6 aluminum with NBR O-rings, each fitting is machined to the 9/16-18 UNF (6AN/AN6 ORB) thread standard and designed for automotive fluid systems like fuel rails, oil coolers, pumps, regulators and filters. The dual sealing method—37° flare on the AN side and an O-ring on the ORB side—provides a compact, serviceable connection where space or port types differ.

How does this adapter seal both types of connections reliably?

The adapter uses two established sealing geometries: the AN side seals by metal-to-metal contact at a 37° flare angle, while the ORB side relies on an NBR O-ring compressed inside the port. That combination gives a tight mechanical seal on the flare end and an elastomeric seal on the ORB end, minimizing potential leaks at the junction.

• AN side: 37° flare seat for metal-to-metal sealing
• ORB side: NBR O-ring provides pressure seal inside the port
• Thread standard: 6AN / AN6 ORB = 9/16-18 UNF

What are the material and temperature limits for these fittings?

The body is precision-machined from 6061-T6 aluminum for strength and corrosion resistance in automotive environments. The included O-rings are made from NBR (nitrile rubber), suitable for common fuels and oils; both materials are selected to balance performance and economy.

• Body: aluminum alloy 6061-T6
• O-ring: NBR rubber compatible with fuels and oils
• Temperature ranges: working -65°F to 252°F; O-ring -4°F to 392°F

What pressure and applications are these adapters rated for?

Each adapter is rated to handle typical pressures found in fuel and oil delivery systems up to 1500 PSI. They are intended for use where AN6 flare lines must interface with AN6 ORB ports—common on aftermarket fuel rails, oil coolers, pumps, regulators and inline filters.

• Working pressure: up to 1500 PSI
• Common uses: fuel rail, fuel pump, regulators, oil cooler, fuel filter
• Packaged as a set of four for multiple connections or spare parts

How do I install and maintain these adapters safely?

Installation requires matching thread size and correct torque for AN fittings—hand-start threads, then tighten to spec with appropriate wrenches to avoid crushing or distorting the flare. Inspect and replace O-rings during reassembly to maintain sealing integrity and check fittings periodically for signs of wear or leak paths.

• Hand-start threads, then tighten to recommended torque values
• Replace O-ring if nicked, hardened, or swollen during service
• Use thread-compatible tools to avoid marring aluminum bodies

Who this is for: These EVIL ENERGY adapters suit mechanics, tuners, and DIY enthusiasts who need to bridge AN6 flare lines to AN6 ORB ports without cutting or re-flaring hoses. They are useful for workshop retrofits, engine swaps, custom fuel systems and routine maintenance where reliable, serviceable connections are required. If your project uses AN6/6AN hardware and you want a compact, machined aluminum adapter with replaceable O-rings, this four-piece set offers a straightforward solution.
